B Correct answer
Explanation

Total balls = 8 + 9 = 17. Probability of drawing a red ball = (Number of red balls) / (Total number of balls) = 8 / 17.

AI explanation

The total number of balls in the urn is 8 red plus 9 black, which equals 17. Using the classical definition of probability, the probability of drawing a red ball is the number of red balls divided by the total number of balls. This gives a probability of 8/17.
